“Cute Crush, Pwede Wag Na Tayo Mag-aral?”

1. Crimping Tool

2. Cable Tester

3. Punch Down Tool

4. Wire Stripper

5. Network Analyzer

6. Tone Generator & Probe

7. Multimeter

What does a crimping tool do?

Attaches RJ45 connectors to Ethernet cables by pressing the metal pins into the wires

What does a cable tester check?

Continuity, wiring sequence, and pin alignment.

What does a punch down tool do?

Inserts and secures wires into patch panels or keystone jacks.

What does a wire stripper do?

Removes cable insulation without cutting/nicking the copper wire

What does a network analyzer measure?

Cable performance, bandwidth, crosstalk, and signal loss

What does a tone generator + probe do?

Sends and detects a signal to trace and identify a cable in a bundle.

What does a multimeter test?

Voltage, resistance, and continuity

What is RJ45?

The standard plug used to terminate Ethernet cables. It is an 8P8C — 8 positions, 8 contacts connector.

T568B color order?

T568A color order- GGOBBOBrBr
White/Green, Green, White/Orange, Blue, White/Blue, Orange, White/Brown, Brown

T568B color order- OOGBBGBrBr

White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown

Which pins does 10/100 Mbps Fast Ethernet use?

Pins 1 & 2 = transmit; Pins 3 & 6 = receive.
Pins 4,5,7,8 are unused.

How many pins does Gigabit Ethernet use?

All 8 pins. Each pair can transmit and receive simultaneously

Cat5e vs Cat6a vs Cat8 speeds?

Cat5e = 1 Gbps

Cat6a = 10 Gbps

Cat8 = 25–40 Gbps

Maximum distance to remember?

Most categories shown are around 100 m, but Cat8 = 30 m;

Cat6 supports 10 Gbps at about 55 m in the slide.
